To all whom it may concern.-

Be it known that I, LOUISE Boson, a citizen of Germany, residing at Munich, Germany, have invented certain new and useful Improvements in Processes of and Apparatus for Saturating Paper-Rolls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the'same.

My invention relates to a method and means for facilitating the saturation of paper-rollsintended for use in roller copying-presses;

and has for its object the avoidance of diflioulties and disadvantages which have heretofore attended the saturation of such rolls.

Thecopying of written or printed matter would be greatly facilitated and cheapened if it could be satisfactorily done by means of the ordinary paper-rolls as found in commerce and designed primarily for other purposes instead of requiring'the use of specially-wound rolls. In consequence of the loose winding of paper-rolls, and particularly those intended for commercial use, it has been experienced that during the process of saturating the same the swelling of the paper causes an uneven displacement of the layers laterally and also a tendency to unwind, the result being that the paper presents an uneven end surface, which not only increases the difficulty of placing the roll in the machine, but also causes an uneven feeding of the paper and resistance to the passage of the same through the machine when drawn longitudinally. Attempts have been made to overcome these objections by saturating the rolls in a partial vacuum, whereby the uneven swelling of the paper is to a certain extent obviated. This method, however, requires the use of cumbersome and expensive apparatus and for this reason is in itself objectionable. I attain the desired object by means of the simple but eflicient apparatus illustrated in the accompanying drawings, in which Figure 1' is a side elevation with thepaperroll in place. Fig. 2 is'an end elevation, and

Fig. 3 is-a top plan view of a preferred form of apparatus, while Figs. 4 to. 14, inclusive,

The apparatus preferably consists of a frame a, the ends of which are composed of circular plates 1), one of which ishinged at c in order to permit the insertion of the paper-roll and when closed is held in that position by means of a spring-catch (1. Each of these end plates is provided with a circular opening e, adapted to receive the spindle or axle f upon which I the paper is wound. Mounted upon a rod g passing through one side of the frame a is a straight edge It, acting under the influence of the bow-spring 7 to press upon the paper-roll m-when in position and prevent the unwinding of the same. The frame is proportioned in size to the paper-roll to be saturated, the relative dimensions being such that when the roll is in place there is no space between the edges .of the rolled paper and the plates forming the end of the frame.

In operation the straight edge It is retracted by means of the handle is, and the roll of paper is inserted through the open end ofthe frame. The end plate is then closed and held in that position by means of the spring-catch d. The frame and the contained roll are then placed in a horizontal or-vertical vessel containing water and left therein a suflicient length of time to permit the moisture to thoroughly permeate all of the layers of paper, the end plates effectually preventing by lateral pressure an uneven swelling of the layers, while the straight edge It precludes any unwinding of the roll. When the saturation is complete,- the roll is removed by releasing the pressure of the straight edge and opening the end plate,

when it is ready to be placed in the copying- 7 general principle of operation will be found suited to particular circumstances.

In Figs. 4 to 14, inclusive, I have illustrated certain forms which I have found to possess advantageous features. In Figs. 4, 5, and 6 are shown modifications, in which the pressure is exerted upon the end of the roll by means of springs. springs d act directly upon the end plates or disks. In Fig. 5 a' bow-spring d exerts In Fig. 4 compression coil- 1 by tension-springs or elastic members 01 In pressure between its two ends upon the disks 6. In Fig. 6 the two end plates are connected Fig. 7 cross-bars d are arranged to adjustably engage with the sides of the frame to securely hold the end plates in position. The

screw-spindle d is used to reciprocate the end plates 6 in Fig. 8. In Fig. 9 the pressure is sure may be brought to bear.

oneof its arms formed as a cam, and in Fig.

14 a lever and link (I are shown.

Having thus fully described my invention, what I .claim as new, and desire to secure by Letters Patent of the United States, is-

1. The method of moistening paper, which consists in subjecting the roll to the influence 'of moisture and at the same time limiting the expansion of the paper lengthwise of the roll. 2. The method of moistening paper-rolls, which consists in subjecting the-roll to the influence of moisture whileunder pressure exerted upon the end of the roll.

3. An apparatus for moistening paper-rolls, comprising a bath. a plurality of plates, and

. means for holding the plates against the ends of the roll.

4. An apparatus for moistening paper-rolls,

- comprising a bath, a plurality of plates having apertures forming bearings for the roll, and means for holding the plates against the ends of the roll. I

5. An apparatus for moistening paper-rolls, comprising a bath, a plurality of plates, means for holding the plates against the ends of the roll, a bar, and yielding means for holding the bar against the surface of the rollin line with the axis thereof.

8." An apparatus for moistening paper-rolls,

.comprisinga bath, a plurality of plates having apertures for the reception of the axle of the roll, means for holding the plates against the ends of the roll, a bar, and yielding means for holding the bar against the surface of the roll in line with the axis thereof.

9. An apparatus for moistening paper-rolls, comprising a frame, end plates mounted thereon, one of the plates being hinged as a door to permit the insertion of the roll, a catch to hold the'hinged plate in its closed position, and a bath arranged to receive the frame.

10. An apparatus formoistening paper-rolls, comprising a frame, plates or disks mounted in the ends of said frame, one of the plates being hinged as a door to permit the insertion of the roll, a spring-catch to hold the hinged plate in its closed position against the end of v the roll, a bar, yielding means for holding the bar against the surface of the roll in line with the axis thereof, and a bath arranged to re ceive the frame.

In testimony whereof I aflix my signature to this specification in the presence of twowitnesses.
